The brands in the Volkswagen Group have shown that they can develop some of the world's best diesel engines for passenger cars. At the Vienna Motor Symposium taking place May 8 and 9, Audi has an updated one to add to its lineup. It's launching a new version of the 3.0 TDI V6 with better efficiency and more power than the version currently in the US.
The new diesel will be offered in two tunes: 215 horsepower or 268 hp. However, Audi isn't giving away all of the new engine's secrets just yet. It says "depending on model" the mill makes as much as 442.5 pound-feet of torque and gets as much as 13 percent better fuel economy. That likely means the more powerful version gets the twist, and the other one has the better consumption, but we'll have to see.
To compare, the current 3.0 TDI offered in the US produces 240 hp and 428 lb-ft of torque. In the A6, it's rated at 24 miles per gallon city, 38 mpg highway and 29 mpg combined, according to the EPA.
To achieve these improvements, Audi packed the engine with technology. It has low-friction piston rings and pins. There are separate coolant loops for the crankcase and the redesigned cylinder heads. Likely the biggest change is that the NOx storage catalytic converter, diesel particulate filter and SCR injection system are combined into a single assembly, which the company claims is a first for automobiles. The upgrades allow it to meet Euro 6 emissions standards.
Audi is also showing a new seven-speed dual‑clutch transmission for models with longitudinal engines and front‑wheel drive in Vienna. The company doesn't say when either product would find its way into new models, though. Scroll down to read more details about them.

Diesel fumes are bad for people. But diesel power is good for a lot of heavy-duty work. So, for now, one answer to threading the needle of that little conundrum is to make diesel engines as clean as pos...
